1.9 tdi audi 80 ECU swap

[Catalin_BN]

Hello guys. I'm the proud owner of a audi b4 1.9 tdi from 1993. Everything runs as smooth as possible but i really want some upgrades but the ECU really stop me from doing that. I have that f****** stupid 55 pin ECU. I can't retrofit cruise control etc. I want a pd manifold, AFN injectors and to tune it proper. I don't want to do that on thia damn stupid ecu. I have a 68 pin ecu immo off from a 80 1995. Please help me to wire it properly for my car. I have the IP from a golf 4 tdi so i can swap the pump top. Help me guys.

Already did try a pinout and it didnt start. I was so stupid...because I didnt hook up a vcds.
Any ideas?

Hey again, I bought a ECU/engine wiring harness from a audi 80 avant from 1995. That car was really loaded with extras like webasto, cgp and everything sweet. Im trying to swap my harness with the new one but I have some connectors to identify. The most ugly one is a 6 pin connector, only 5 of them user in the engine bay, and it is almost the same length like the injection pump cable. Please help guys!



L.E. It might be something about AC ?
